How to Build a Geodesic Dome in RISA-3D?

In modeling what would be a rather difficult geometric structure, by using the High Level Generation tool in RISA-3D, a geodesic dome can be constructed rather quickly and easily.

  1. Select the High Level Generation button Geo Dome_1 , and then select the Geodesic Dome option:Geo Dome_2
  2. The following dialog box will be displayed and you can enter in the necessary information for the geodesic dome generation:

Geo Dome_3
Platonic Solids:Designate the number of faces of the geodesic dome.

Triangle Subdivision:Designate the number of triangle submesh per side of the triangular plate.

Geodesic Geometry Properties:  Set the radius and dome height.

Geodesic Origin:Choose the dome origin coordinates.

Member:Check the Generate Members? box to create strut members.  Designate the member prefix, a section set defined in your Section Sets spreadsheet, and the local x-axis rotation of the members.

Plates:  Check the Generate Plates? box to create exterior plate members.  Designate the plate prefix, a general material defined in your Materials spreadsheet, and the thickness of the elements

 

3.  Click OK and the program will apply this information to create the geodesic dome structure.
